This 3-foot T8 LED tube is available in ballast-compatible (Type A), ballast-bypass (Type B), and universal models that support either option. Ballast-compatible versions work only with electronic instant-start or rapid-start T8 ballasts, while ballast-bypass models require direct line-voltage wiring. Magnetic and T12 ballasts are not supported, so ballast type should always be verified before installation.
